Slots API: 18,000+ slot games, one connection.

A slots API is the technical bridge between your casino platform and the studios that build slot games. Instead of hosting games yourself or wiring a separate connection to every provider, your platform talks to one interface: it requests the game list, launches sessions, settles bets and wins against your wallet, and pulls the numbers for reporting — all over standard HTTPS calls.

The point is what you no longer have to do. No per-studio protocols, no separate certification round for every new provider, no fleet of connections to keep alive. The IGP slots API sits on top of our casino game aggregator, so one connection carries the entire slot catalogue — and when a new studio joins the network, it shows up in your back office as a switch.

Under the hood it is a seamless-wallet model: games run on the providers’ servers, and every bet and win settles against your player wallet in real time through the API. Your platform stays the source of truth for accounts, balances and bonuses; the API handles game delivery, session security and provider communication.

This page covers the slots vertical specifically. If you are looking at the whole lobby — live dealer, crash and sportsbook on the same connection — that is documented on our main casino API page, with the step-by-step technical flow in the API integration guide.

Slots are the engine of every online casino. They take the majority of play, they are what players search for by name, and the depth of the lobby decides whether a brand feels alive or empty. That makes slot content a strategic problem: you do not just need games, you need the right games per market, refreshed constantly, without your team drowning in supplier management.

A slots API solves the scale side. One connection puts the whole slot market in reach — 18,000+ titles from 150+ studios — and every new release from a connected provider lands in your catalogue on its own. Your team stops chasing content and starts curating it.

It also solves the data side. Every game arrives with consistent metadata — RTP, volatility, features, themes, thumbnails — across all providers. That is what lets you build smart lobbies: a high-volatility row for the stream crowd, a classic-reels section for traditional players, portrait-mode games for mobile-heavy markets, seasonal promos assembled in minutes rather than days.

And because everything settles against your own wallet in real time, you keep control of balances, bonuses and reporting. The API delivers the games; your platform stays the source of truth.

New regimes no longer stop at who holds the licence — they write rules into the game client itself. Autoplay restrictions, forced breaks in play, session alerts and per-market feature limits are now normal conditions of operating, and every one of them turns into a per-title question: does this game support it, and if not, does it stay in the lobby?

Answering that studio by studio is where market launches slip. Through one API it is a configuration exercise: you switch providers and individual titles on or off per jurisdiction, and the catalogue each region receives is exactly the one you approved.

The same control covers the commercial side — bonus-buy availability, demo play, jackpot eligibility and game-level restrictions all sit in the same back office rather than in a stack of supplier emails.

If you are preparing an entry into a newly regulated market, our operator guides walk through the sequencing, and the casino platform can carry the same content layer if you would rather not build the front end at all.

Established operators use it to widen an existing lobby without touching their platform: keep your wallet, your bonusing and your reporting, and switch on thousands of extra titles per market. If your current supplier covers only a handful of studios, this is how you close that gap in one project.

New casino brands use it to launch complete. Rather than opening with twenty games and adding more for a year, a new brand goes live with a full lobby on day one. Our launch guide covers how that fits the wider build.

Platform providers and white-label operators use it as their content layer, serving every brand on the platform from one connection and configuring the catalogue per client and per market. One supplier relationship, many storefronts.

Sportsbook operators use it to add a casino alongside betting on the same wallet — the highest-value cross-sell in iGaming, since a bettor who spins between matches is worth far more than one who only bets. It sits next to our sportsbook software on the same stack.

You will see the same thing called three names. Slots API is the industry term for the interface that delivers online slot games to a casino platform. Slot game API means exactly the same and is common in developer searches. Slot machine API usually comes from teams with a land-based background — the machines here being the digital descendants of cabinet reels, from studios like Novomatic and EGT that built both.

Whichever term you searched for, the thing you need is the same: a documented interface that returns the game catalogue, launches secure sessions on any device, and settles bets and wins against your wallet in real time. That is what this page describes — 18,000+ online slots from 150+ studios, delivered through one connection and managed from one back office.
